  • through SQL query, i’ve to concatenate multiple rows into single row with comma-separator. Help me how to write a coding for it.

    Ex. the column is like wise
    ID Name
    1 Arthi
    2 Preethi
    3 Madhu

    now it should be Arthi,Preethi,Madhu in a single row.

    • declare @s varchar(100)
      set @s=”
      select @s=@s+description+’,’ from gender
      if len(@s)>0
      select left(@s,len(@s)-1)

  • Other method

    select specific_name,specific_schema from information_schema.routines
    where routine_type=’function’

  • Arthi

    Try this

    declare @s varchar(8000)
    select @s=coalesce(@s+’,’,”)+name from your_table
    select @s

    Also, your question is no way related to this article
    If you have any general question to ask post at http://www.sqlserverperformance.com/forum

  • I need to be able to take the results of your query and make a script to recreate all those functions on another server…is that possible?

  • I thinks this will also work

    SELECT b.name fncSchema, a.Name AS function_name
    FROM sys.objects a
    INNER JOIN sys.schemas b
    ON a.schema_id = b.schema_id
    WHERE TYPE in (‘FN’, ‘IF’)

  • @Kalpesh – it’s actually

    SELECT b.name fncSchema, a.Name AS function_name, TYPE
    FROM sys.objects a
    INNER JOIN sys.schemas b
    ON a.schema_id = b.schema_id
    WHERE TYPE in (‘FN’, ‘IF’, ‘TF’)

  • Is there any such function that check exactly Numeric values. isnumeric() is there but it arithmetic operators as numeric like * , – , / , * , .
    I want it should check 0-9 and return True else False

    • Try this logic

      select case when col not like ‘%[^0-9]%’ then is_numeric else non_numeric end as col from your_table

  • select case when col not like ‘%[^0-9]%’ then is_numeric else non_numeric end as col from your_table

  • multiple value comman operator

    select *into(select *from split(tablecolumnname)as number table1)from table1

  • Is there a way to find out the author of the user defined function?

  • Hi All,
    I have posted one query lately but didn’t get any reply. So I am posting another post here.
    Can you post a query where we can find any object like either it’s a funcion or a view or any other object in a server having n number of databases.It should mention the datbase name,schema and also shows the the dependencies like if it is used in any stored procedure/view or in any sql jobs.

  • Hi,
    The above script gives function_name, schema name and type
    But, i need Parameters and Datatypes of the functions. Can you script it out please


    • You can use sys.all_parameters catalog view and put filter for function name

      select * from sys.all_parameters where object_id = object_id (‘AddNumbers’)

  • we can user sp_helptext StoredprocedureName this command , shows the sp’s but

    HI All,

    Please help me , I want to make a user define functions in sql server but i don’t know how to make this.

    because there is a confusion in @parameter and define @variable why we use the this .

    supposed we are using parameter in function then why we need to use variable .

    if you will give me a relevant answer then it would be a big big help for me.
